Galaxy S 4 smartphones that support LTE will use the Qualcomm chip, while those that support only 3G will use a Samsung chip

The Samsung Galaxy S 4 will be powered by a quad-core, 1.9GHz Qualcomm Snapdragon 600 processor, the company has confirmed -- at least those using LTE 4G radios. Non-4G models of the S4 will be powered by Samsung's own Exynos 5410 Octa processor.
